- York Power Storage desires to construct a $2.1 billion, 1,000-acre dam and energy turbine venture on the Susquehanna River in York County, Pennsylvania. The venture entails creating a brand new reservoir that may require flooding 600 acres, and constructing a 1.9-mile-long, 225-foot-high dam and two smaller dikes.
- The Studying, Pennsylvania-based firm utilized in February to run a feasibility examine for the hydroelectric plant. The Federal Power Regulatory Fee mentioned the software is incomplete, per WGAL, however the firm has time to resubmit.
- The venture would displace greater than 40 properties, in line with WGAL, to the chagrin of householders within the space. This isn’t the primary dam proposal within the area. Related initiatives in 1990 and 2011 acquired giant pushback and have been finally dropped.
York Power Storage has touted the advantages of the clear power the venture would produce for the 13-state regional energy grid, in line with LancasterOnline, although such dam and reservoir builds nonetheless disrupt the surroundings. York Power Storage’s proposal says the brand new plant would churn out as much as 8,560 megawatt-hours in a 10-hour cycle, sufficient to energy a metropolis of half one million folks.
The power would act as storage for power that may be tapped when energy just isn’t being generated by wind or photo voltaic sources. Water is pumped uphill to a reservoir utilizing surplus energy generated throughout peak durations, and that water then generates electrical energy by touring by way of generators when there’s a energy deficit, an idea known as “pumped storage.”
The power would take a number of years to finish, York Power Storage mentioned, and have a 50-plus-year lifespan.
Fewer huge dam builds, extra remediation and elimination
Though some huge dams are nonetheless being constructed, the heyday for these kind of initiatives is probably going over. Worldwide, building of huge dams fell from a late-Nineteen Seventies peak of about 1,500 a 12 months to 50 per 12 months in 2020, a 2021 examine from United Nations College’s Institute for Water, Surroundings and Well being exhibits. There’s a rising understanding of the hurt dams could cause to ecosystems and of the hazard they pose to space residents and companies when they’re now not stored as much as code — which many will not be.
The UN report discovered that globally, “tens of 1000’s of current giant dams have reached or exceeded an ‘alert’ age threshold of fifty years, and lots of others will quickly strategy 100 years. These aged constructions incur quickly rising upkeep wants and prices whereas concurrently declining their effectiveness and posing potential threats to human security and the surroundings.”
Within the U.S. alone it will value $157.5 billion to rehabilitate its 88,616 poor non-federal dams, a current report by the Affiliation of State Dam Security Officers exhibits, which is way better than the funding out there to take action. ASDSO estimates the value tag to remediate simply the nation’s most crucial dams is $34.1 billion.
Dam remediation and elimination efforts are at the moment getting a lift from the 2021 Infrastructure Funding and Jobs Act, which incorporates $4 billion over 5 years for such initiatives. In the meantime, dam elimination initiatives are rising extra quite a few — the largest dam elimination venture within the nation’s historical past is about to kick off on the Klamath River in California and Oregon.
